When deploying your APK, you will be redistributing object code from xbrt_android.jar. Be aware that some of the binary code included in that JAR is covered by the GNU General Public License with "classpath" exception. Be sure to meet your obligations under section 3 of the license (which discusses source code availability). Note that we have provided you with the source for the code falling under the GPL in java/xbrt_android_open_src.zip.

Be careful not to redistribute runtime_src.zip (available in licensed kits only), which includes proprietary code that is not licensed for source redistribution.
